Objectives: The application of Central Venous Catheters (CVC) is associated with increased risk of microbial colonization and infection. The aim of present study was to assess the frequency of pathogens colonizing CVC and to determine their susceptibility pattern to various antimicrobial agents. Materials and methods: A total of 253 samples of CVC from intensive care units (ICU) patients were received for culture during 2003. All microorganisms were identified by standard microbiological methods and the susceptibility to antimicrobial agents was determined according to NCCLS recommendations. Results: A total of 184 (72.7%) cultures were positive and 223 pathogens were isolated. Coagulase negative staphylococci (CNS) were the dominant isolates (24.7%), followed by Enterobacter spp. (12.1%), Pseudomonas spp. (11.7%), Enterococcus spp. (9.9%), Klebsiella spp. (8.6%), Candida spp. (7.6%), Acinetobacter spp. (7.6%), other Gram negative nonfermentative bacilli (5.8%), Serratia spp. (4.5%), Staphylococcus aureus (2.6%), Proteus mirabilis (2.2%), E. coli (1.8%) and Citrobacter spp. (0.9%). Meropenem (84.5%) and vancomycin (100%) remain the most effective antimicrobial agents against Gram negative and Gram positive bacteria, respectively. Conclusion: Gram negative bacilli and CNS are the commonest microorganisms colonizing CVC from ICU patients. The increasing resistance of the bacteria to antimicrobial agents is the major problem in spite of restricted policy of using antimicrobial agents in ICU.

Abstract Background Ventilator-associated pneumonia (VAP) is the most common hospital-acquired infection (HAI) in intensive care units (ICUs). Ventilator-associated event (VAE), a more objective definition, has replaced traditional VAP surveillance and is now widely used in the USA. However, the adoption outside the USA is limited. This study aims to describe the epidemiology and clinical outcomes of VAEs in China, based on a prospectively maintained registry. Methods An observational study was conducted using an ICU-HAI registry in west China. Patients that were admitted to ICUs and underwent mechanical ventilation (MV) between April 1, 2015, and December 31, 2018, were included. The characteristics and outcomes were compared between patients with and without VAEs. The rates of all VAEs dependent on different ICUs were calculated, and the pathogen distribution of patients with possible VAP (PVAP) was described. Results A total of 20,769 ICU patients received MV, accounting for 21,723 episodes of mechanical ventilators and 112,697 ventilator-days. In all, we identified 1882 episodes of ventilator-associated condition (VAC) events (16.7 per 1000 ventilator-days), 721 episodes of infection-related ventilator-associated complications (IVAC) events (6.4 per 1000 ventilator-days), and 185 episodes of PVAP events (1.64 per 1000 ventilator-days). The rates of VAC varied across ICUs with the highest incidence in surgical ICUs (23.72 per 1000 ventilator-days). The median time from the start of ventilation to the onset of the first VAC, IVAC, and PVAP was 5 (3–8), 5 (3–9), and 6 (4–13) days, respectively. The median length of hospital stays was 28.00 (17.00–43.00), 30.00 (19.00–44.00), and 30.00 (21.00–46.00) days for the three VAE tiers, which were all longer than that of patients without VAEs (16.00 [12.00–23.00]). The hospital mortality among patients with VAEs was more than three times of those with non-VAEs. Conclusions VAE was common in ICU patients with ≥ 4 ventilator days. All tiers of VAEs were highly correlated with poor clinical outcomes, including longer ICU and hospital stays and increased risk of mortality. These findings highlight the importance of VAE surveillance and the development of new strategies to prevent VAEs.

Background: Antimicrobial resistance is one of the research priorities of health organizations due to increased risk of morbidity and mortality. Outbreaks of nosocomial infections caused by carbapenem-resistant Acinetobacter Baumannii (CRAB) strains are at rise worldwide. Antimicrobial resistance to carbapenems reduces clinical therapeutic choices and frequently led to treatment failure. The aim of our study was to determine the prevalence of carbapenem resistance in A. baumannii isolated from patients in intensive care units (ICUs). Methods: This cross-sectional study was carried out in the Department of Microbiology, Basic Medical Sciences Institute (BMSI), Jinnah Postgraduate Medical Centre (JPMC), Karachi, from December 2016 to November 2017. Total 63 non-repetitive A. baumannii were collected from the patients’ specimens, admitted to medical and surgical ICUs and wards of JPMC, Karachi. The bacterial isolates were processed according to standard microbiological procedures to observe for carbapenem resistance. SPSS 21 was used for data analysis. Results: Out of the 63 patients, 40 (63.5%) were male. The age of the patient ranged from 15-85 year, with average of 43 year. 34.9% patients had been hospitalized for 3 days. Chronic obstructive pulmonary disease was present in highest number with average of 58.7% for morbidity. Number of patients on mechanical ventilation was highest (65.1%). All isolates were susceptible to colistin. The resistance to ampicillin-sulbactam, ceftazidime, ciprofloxacin, amikacin, piperacillin- tazobactam and meropenem was 82.5%, 81%, 100%, 87.3%, 82.5% and 82% respectively. Out of 82% CRAB, 77% were obtained from ICUs. Conclusion: This study has revealed the high rate of carbapenem resistance in A. baumannii isolates in ICUs thus leaving behind limited therapeutic options.

Abstract Background Hospital-acquired infections (HAIs) in intensive care units (ICUs) are among the avoidable morbidity and mortality causes. This study aimed at investigating the rate of ICU-acquired infections (ICU-AIs) in Iran. Methods For the purpose of this multi-center study, the rate of ICU-AIs calculated based on the data collected through Iranian nosocomial infections surveillance system and hospital information system. The data expanded based on 12 months of the year (13,632 records in terms of “hospital-ward-month”), and then, the last observation carried forward method was used to replace the missing data. Results The mean (standard deviation) age of 52,276 patients with HAIs in the ICUs was 47.37 (30.78) years. The overall rate of ICU-AIs was 96.61 per 1000 patients and 16.82 per 1000 patient-days in Iran’s hospitals. The three main HAIs in the general ICUs were ventilator-associated events (VAE), urinary tract infection (UTI), and pneumonia events & lower respiratory tract infection (PNEU & LRI) infections. The three main HAIs in the internal and surgical ICUs were VAE, UTI, and bloodstream infections/surgical site infections (BSI/SSI). The most prevalent HAIs were BSI, PNEU & LRI and eye, ear, nose, throat, or mouth (EENT) infections in the neonatal ICU and PNEU & LRI, VAE, and BSI in the PICU. Device, catheter, and ventilator-associated infections accounted for 60.96, 18.56, and 39.83% of ICU-AIs, respectively. The ventilator-associated infection rate was 26.29 per 1000 ventilator-days. Based on the Pabon Lasso model, the lowest rates of ICU-AIs (66.95 per 1000 patients and 15.19 patient-days) observed in zone III, the efficient area. Conclusions HAIs are common in the internal ICU wards. In fact, VAE and ventilator-related infections are more prevalent in Iran. HAIs in the ICUs leads to an increased risk of ICU-related mortality. Therefore, to reduce ICU-AIs, the specific and trained personnel must be responsible for the use of the devices (catheter use and ventilators), avoid over use of catheterization when possible, and remove catheters earlier.

This study aimed to describe the experiences of patients with COVID-19 admitted to the intensive care units (ICU). The data were analyzed by content analysis on 16 ICU patients with COVID-19. Data were collected by semi-structured interviews. Three categories were identified: (a) captured by a challenging incident with subcategories: perceived sudden and challenging death, fear of carelessness in overcrowding, worry about the family, and frustration with stigmatizing; (b) the flourishing of life with subcategories: spiritual-awakening, resilience in the face of life challenges, promoting health behaviors, and striving for recovery; and (c) honoring the blessings with subcategories: understanding the importance of nurses, realizing the value of family, and realizing the value of altruism. COVID-19 survivors experienced both positive and negative experiences. The results of this study could help health care providers identify the needs of ICU patients with COVID-19, including psychological, social, and spiritual support and design care models.

Because of importance of Hospital acquired infections (HAIs), it is critical to conduct surveillance studies to obtain the required data about the regional microorganisms and their susceptibility to antibiotics. This study to investigate antimicrobial resistance pattern among Intensive Care Unit (ICU) patients in a private medical college hospital setup. In a cross sectional study, 100 specimens from patients admitted in the ICU who had signs or symptoms of nosocomial infection were collected from 2012 - 2013. For each patient, samples of blood, urine, tracheal aspirate, sputum, wound swab, pus, and endotracheal tubes were obtained, cultured and analyzed with antibiogram. The most common primary diagnosis were aspiration pneumonia (49%) and UTI (20%) respectively. The most common locations for infection were tracheal aspirate (54%). The most frequent gram negative microorganisms derived from samples were Acinetobacter spp (29%), Klebsiella spp (26%) and Pseudomonas spp (18%). Klebsiella spp, Acinetobacter spp and Pseudomonas spp were most common resistant organisms among all. Klebsiella spp were resistant against Ceftriaxone (84.6%), Ceftazidime (82.6%), Amikacin (46.1%), Gentamicin (66.6%) and Quinolones (65-66.6%) respectively. Acinetobacter spp were resistant against Ceftriaxone (85%), Ceftazidime (88.8%), Cefotaxime (85.7%), Meropenem (79.3%),Amikacin (86.2%), Gentamicin (84.5%) and Quinolons (86.2-89.2%) respectively. Pseudomonas spp were resistant against Ceftriaxone (70.5%), Ceftazidime (66.6%), Amikacin (68.7%), Gentamicin (58.8%), Meropenem (52.9%) and Quinolones (81.2-86.6%) respectively. Meropenem was the most sensitive antibiotic against Klebsiella spp (84.6%) but Cotrimoxazole in case of Acinetobacter spp (60%) respectively. Escherichia coli were mostly isolated from urine, which was sensitive to Amikacin (73.3%) and Meropenem (86.6%) respectively. Gram-negative pathogens obtained from ICU patients in our settings show high resistance to antibiotics. Regular monitoring of the pattern of resistance of common pathogens in the ICUs is essential to up-to-date the use of rational antibiotics regiments.Bangladesh J Medicine Jul 2014; 25 (2) : 47-51

Candidemia is becoming more actual because of better survival of even critically ill patients, wide use of antimicrobials, and increased numbers of invasive procedures and manipulations. Diagnosis of candidemia remains complicated, and costs of treatment and mortality rates are increasing. Objective. To evaluate the pathogens of candidemia, risk factors and their influence on outcome. Material and methods. Data of 41 patients with positive blood culture for Candida spp., who were treated in the intensive care units at the Hospital of Kaunas University of Medicine, were analyzed retrospectively. Results. Candidemia was caused by Candida albicans (C. albicans) in 48.8% (n=20) of patients and by non-albicans Candida in 51.2% (n=21) of patients. The main cause of candidemia was C. albicans in 2004 (83.3%, n=5), but in 2005 (63.6%, n=7), in 2006 (57.1%, n=4), and in 2007 (52.9%, n=9), the main cause was non-albicans Candida spp. The number of candidemia cases caused by C. albicans was decreased in 2005, 2006, and 2007 as compared with 2004, and the number of candidemia caused by non-albicans Candida spp. was decreased, respectively (P<0.05). More than 65% (n=34) of patients had severe disease (P<0.05). Lethal outcome was recorded in 58.5% of patients with candidemia. Mechanical ventilation was used in 76.9% (n=20) and urinary bladder catheter in 72.1% (n=19) of non-survivors and in 23.1% (n=6) and 26.9% (n=7) of survivors, respectively (P<0.05). Conclusions. There is an increase in the prevalence of candidemia in the intensive care units during the 4-year period; half of candidemia cases were caused by non-albicans Candida spp., and patients with candidemia caused by non-albicans Candida spp. are at higher risk of mortality. Therefore, for the empirical treatment of septic conditions in an intensive care unit, when invasive fungal infection is suspected, we recommend using an antifungal agent of non-azole class until a pathogen of candidemia is determined. Severe disease is evaluated as a risk factor for candidemia. Patients with oncological diseases are at significantly higher risk for candidemia caused by non-albicans Candida spp. Use of mechanical ventilation and urinary bladder catheter is a risk factor for lethal outcome.
